@abi.encode

ABI-encode values given a comma-separated type list, like Solidity abi.encode.

On-chain (@abi.encode!): Live values must be elementary static types, at most 4 per call; dynamic, array and tuple types only encode when every value is constant.

Returns: bytes

Syntax

@abi.encode(types ...values)

Arguments

Name	Type	Description
types	string	Comma-separated Solidity types (e.g. uint256,address)
[...values]	any	Values to encode, one per type

Examples

# Encode values without a selector
set $data @abi.encode("uint256,address" 100e18 0x44fA8E6f47987339850636F88629646662444217)
print $data

On-chain face (@abi.encode!)

Standard encoding of static types is their 32-byte head words concatenated, so the face is one concat over full-width word parts — constants fold into hex runs, live words splice in place. Dynamic types (string, bytes, arrays, tuples) re-encode through offsets, which is the recursive re-encoder the core deliberately lacks: a call containing one refuses unless every value is constant, in which case the whole call folds at composition. For raw byte-appending of live dynamic values, use @abi.encodePacked!.
